Polymorphism in Java means you can have many methods with the same name. If it's the same name with the same parameters it will prioritize which one to run. Polymorphism in Java is one of the trickiest topics, but it's not bad once you practice it!
I hope you enjoyed this java polymorphism tutorial!

Alex: "What can birds do?
Me: "Fly obviou.."
Alex: "Sing"
Me: "....."
hahaha
LOL
It's easier to print singing than flying...
I thought the same thing lol
@@DanielADickey Well, it would be something like:
Bird "Flap, Flap, Flap"
Robin "Flap,Flap,Flap,Flap,"
Pelican"Flap, Flap, Flap"
I understand you more easily than my lecturers
😭😭😭🙏My first response ☕. U just made my evening.
@@striemmpegs Yea he's still better than any of my CS Teachers! :D
Underrated comment
Its not that weird when all of my CS teachers are 60 years old ++
Because he understands it better than our lecturers
Petition for Alex to create a Patreon for the solve purpose of uploading the video footage of him saying: "KWAAH KWAHAH KWAHA".
where do I sign
😂😂❤
Its like 1 am and I'm cramming for an exam, didn't expect to hear that sound at 4:04
Haha I get you.. same here :D
But it help release my stress 🤣
I'm new to coding and I'm struggling my way through learning to code. Whenever I search a topic and see your face I instantly feel better. Thank you for being awesome. Even though you stopped doing them. Your passions are important and very cool. You're awesome!
0:23 Polymorphism meaning and context (many forms of a method)
1:33 Going from one form of a method to many and how polymorphism comes in
1:50 Using inheritance to create another bird with the same sing method (e.g. with a sub-type of a bird)
3:30 When 2 instances the same method are used, prioritises the one in the same class
4:05 perfectly cut scream
4:05 When alex made the kwah sound that he's never repeating in his life.
This is flawless. I just spent 2 hours in a lecture and not understand anything and you taught me polymorphism in 5 min. I subscribed.
This guy explained 200 pages of my inheritance and polymorphism module in just freaking 5 mins... I'm switching to this professor haha
You deserve a medal of honor for being a top-notch Java teacher!
It's just amazing how you take such complex concepts and make them so simple! Thank you so much!
Alex, I have big news! I have officially finished watching of your Java tutorial playlists and man, all I can say is Thank You So Much!! The way you explained each topic clearly and in a way that is easily understandable was so so so helpful! Thank you for calming us down as well at the beginning of some of the videos 😅 You are so so great and I really appreciate all your help Alex! Good luck to you ♥
Just completed the intermediate playlist with this video. Travelled a long from Basics 1, 2 to intermediate . I kept on practicing along with you - it was an awesome experience all together. Will start with the last playlist of practice programs now . Thanks so much Alex - Stay healthy and fit and keep making awesome videos like this
You made the concept of polymorphism so much easier to understand, i've been struggling for an hour with my textbook until i gave up and went to youtube. Thank you so much for making this video Alex!
The timing of this video release is impeccable. We had our discussion on polymorphism today and i understood none of it. Thank you for being my actual teacher!!! 😂❤
I'm learning coding & your videos help me out soooo much!!!! If I'm overwhelmed, I just search the topic in your videos & I feel so much better! Your way of explaining makes it so much easier to understand! thank you dude!
Hey Alex. You make some great content dude. In fact, I recommend my computer science friends to watch your content. Keep it up dude
Could not wrap my head around several concepts, you just made it so clear. I saw your explanation of Abstraction, and now this one. Thank you. Big Thumbs up, and THANK YOU. Going to watch more. So many youtube videos and sites I went to and a lot of them explained it so that you could almost understand it, but your explanation nailed it.
Today, just finished watching all your Java videos from Java basics 1 to Intermediate, after one week, I can fully admit that Alex has helped me understand Java concepts which I was struggling with before. Thank you so much for your hard work and dedication.
Bro we spent about an hour learning about polymorphism in class yesterday and i still didnt understand. You explained so much more clearly than my professor in less than 5 minutes.... thank you!
Wow. I can't believe how you made it so easy to understand in minutes! I appreciate it! I listened polymorphism from two different teachers (even one of them was in my native language) I didn't understand it yet more confused. But you made it crystal clear. 💐💐💐💐
Glad found this channel, just watched a few vids and I'm understanding code better than most my lectures thank you.
I love videos like you that explain things succinctly, while covering every topic. Keep up the good work!
I have watched many videos to understand polymorphism...and u made it so easy. .thankyou...
Thanks man ,you are making the concept soo clear and understandable keep rocking
I'm kind of new in java and everytime i need to learn something new i check this videos. You are great, so simple to understand and extremely comfortable to repeat the code. Maybe the only thing that can be useful is to have also a file that includes the code that you did in the end of the video, cause sometimes i check the lessons 2-3 times and having the text written (also in a text edit idk) could be awesome. thank you so much for the great work, you are AWESOME!
Omg I love you! I've spent the last 3 days trying to understand this and all I get are triangles or car examples, both which I hate. This was so much more to the point! I feel I can move on! Thank you!
Thanks Alex, I'd love to see more vids from you about this topic. They're solid!
I love the cut off just as you made the sound of a Pelican, that made the video so hilarious which I never would have expected from a Java tutorial. I really appreciate the work you do!
DUDE!!! This is the best explanation I have seen. This is going to be what I use to explain it in my interview tomorrow.
This guy makes me want to properly learn Java.
Teaching style is so easy to understand.
Give this man a medal!
THANK YOU!!! I've been wracking my head for the last hour and your video helped me finally understand !
Bro! Thanks for this tutorial. For years, I have struggled with understanding polymorphism be cause lecturers have habit of going zig zag ways in explaining something that’s supposed to be simple. For the first time I am able to clearly understand and apply polymorphism. You’re simply the best! Good job at the KWAA KWAA KWAA 😀.
Straight to the point. Perfect
Happy found you mann !! Im learning this just now. Thanks, bro.
Thank you! I’m finally understanding how extends works!
You have been a God() send during my Java classes. Thank you for your time and efforts.
Straight to the point and simple. Thank you bro.
Thank you for these videos. Going to college online, the material and access to professors is never consistent or the best quality. These have helped me so much.
I read a section of my book, about the polymorphism but didn't got it right, but now I have the best understanding, thank you.
Thank you, I have a interview tomorrow. I prepared it with your videos. You are making very easy to understand probably because of your super understanding of concept...
You couldn't have posted this at a better time lol I really needed this right now thank you so much!!
Wow I was just looking for a polymorphism video from you on Tuesday!
Straight to the point and understandable, none of this 50 minute lecture type of thing on one topic like my college
Love your channel, after i read something from the book, i do some exercises, and then i also watch a videos related to the topic
I was reading on polymorphism forever and didn't grasp the concept... at all! then I watch your video and understand it in 5 mins! thanks so much!! :)
I AM LEARNING THIS RIGHT NOW, thank you for uploading this!!!
thank you so much for taking your time to share usefull info. I live in Denmark. Im gonna share your channel with my classmates.
You taught me Polymorphism while I'm in university. Thank you!
Hi Alex! Thanks for sharing your point of view!
The lessons shine a different light on the subjects you discuss, which is helping me understand things so mutch better!
I have a request, could you maybe spend some time on Java Collections Framework?
Cheers!!
Keep making these great videos!
bro i was watching your old JAVA LOOP VIDEOS and you are just amazing
JUST AMAZING
love your explanation bro
thx a lot bro AND love FROM INDIA
Uhu! It was really easy to understand polymorphism with you, Alex! Thanks a lot!
I'm studying Computer Science at RUC in Denmark, and this video is part of my curriculum on 2. semester :)
Great video!
4:05 YOU DARE CHALLENGE THE PELICANS?!
So much better than my professor. Your video saved my final! Thank you!
For me the crucial part was one sentence when you said that method with many forms.From there it was easy to take everthing. Thank you
i wish i found this channel when i was in first year cs lol...i struggled so damn much because the profs convoluted everything.
Thank you. I wasn't able to fully understand my lecture notes. But after watching your videos I've been able to do the practical questions without having to look at their notes(I do anyway obviously)
Thanks man your efforts are truly appreciated. Cheers!!
Hi Alex thank you for this videos because I started to understand it way much better than my 2 hours of lecture session. May I request a video about overriding and overloading more detail about it?
This is a great video for understanding poly. good reference material.
thank you so much alex ur absolutely saving my cs marks
Excellent fabulous exciting wow way of explaining polymorphism. I know nothing of java and not even basic syntax. But I understood polymorphism clearly from it. Thanks broh.
From Bangladesh
I am taking Computer science II and your videos have really helped me.

You’ve outdone yourself m8 Thank you this was very helpful. Keep up the good work. Same goes for the inheritance vid
I am in my 1st year of college of SoftDev and honestly I knew how to use it but did not understand HOW it worked. Now it makes sense. Thanks
